BIOS image for the AMD version of the Acer Aspire 4520, with the name referring to MCP67MV A2, the NVIDIA MCP67 chipset revision found on this board. The file is a 1.00 MB binary sized for an 8 Mbit SPI flash. Matching the chipset revision matters, as dumps from Intel versions or other chipset steppings of the same model will not work. Use a programmer such as CH341A to read and save the original chip, then write this image and verify it before testing whether the system powers up and shows video.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @abgm_manutencao_bios. Enginerys does not host this file.
